Deep soil 25-30cm, mu application of rotten high-quality farm fertilizer 3000kg, 20 kg of ternary compound fertilizer. The officers and soldiers raked thin and flattened, making a border 1.2 meters wide for cultivation.

2. Seed collection and direct seeding cultivation method: after the dandelion seeds are ripe in spring, about May-June, harvest the seeds, dry them, remove the crown hair, and store them in a cool and ventilated place before the dew is dry at 8-9 am every day.

3. Sprouting: soak the seeds in clean water for 2 hours, remove them, moisturize and germinate under the condition of 15-20 ℃ (the budding temperature should not exceed 25 ℃). Otherwise, it is difficult to germinate, or even not germinate, and the germination rate can reach more than 95% after 5-8 days.
